NEW YORK (AP) -- Justin Bieber is standing by his manager, who surrendered to police in connection with a mall fan frenzy last year that sent five people to a hospital with minor injuries.

Scott "Scooter" Braun pleaded not guilty Wednesday to charges of reckless endangerment, criminal nuisance and endangering the welfare of a child.

Bieber is a 16-year-old singing sensation. He says in a statement to The Associated Press on Wednesday night that he is "100 percent behind my manager." He says the decisions Braun made the day of the concert were to protect Bieber and his fans.

Bieber was to appear at a mall on New York's Long Island in November. Police canceled the event when the crowd became unruly. Authorities say Braun didn't send out a tweet fast enough to let the crowd of 3,000 know Bieber wouldn't be there.
